RA3 - Kasco Robust-Aire Pond Aeration System

Item #: RA3-NC
OUR PRICE: $2,789.00

Secret To Pond Excellence

An aerator is a must-have for every pond that is meant to stay clean and healthy. This Kasco Robust-Aire is the best option if you own a deep pond (from 8 to 50 feet), and you want to avoid bad odors, muck, algae and fish kills. 

It has been designed to work from under the water, so there’s no disturbance in the landscape. It pumps the water from the bottom directly to the top without any major disturbances to the water flow.

This highly efficient unit works in the deeper waters better than any fountain or high-volume surface aerator. What’s more, it consumes very little energy so it’s not only not expensive to buy, but also to keep. 

This RA3 model comes in three variations: with large base mount cabinet, with post-mounted cabinet, or with no cabinet at all (if you already have some kind of structure and you only need a compressor).

It’s also 100% safe because there’s no electricity in or anywhere near the water. It can be installed remotely and also, instead of electricity, it may receive air. 

Plus, you get a 3-year warranty on each part. We are ready to answer all your questions so don’t hesitate to contact us.
